Endogenous retroviruses: Still active after all these years?
نویسنده
چکیده
Embedded in the genomes of all vertebrates are the proviral remnants of previous retroviral infections. Although the overwhelming majority has suffered inactivating mutations, current research suggests that members of one family of human retroelements may still be capable of movement.

Foamy-like endogenous retroviruses are extensive and abundant in teleosts
Recent discoveries indicate that the foamy virus (FV) (Spumavirus) ancestor may have been among the first retroviruses to appear during the evolution of vertebrates, demonstrated by foamy endogenous retroviruses present within deeply divergent hosts including mammals, coelacanth, and ray-finned fish. If they indeed existed in ancient marine environments hundreds of millions of years ago, signif...
متن کاملTranscriptional Activity of Human Endogenous Retroviruses in Human Peripheral Blood Mononuclear Cells
Human endogenous retroviruses (HERVs) have been implicated in human physiology and in human pathology. A better knowledge of the retroviral transcriptional activity in the general population and during the life span would greatly help the debate on its pathologic potential. The transcriptional activity of four HERV families (H, K, W, and E) was assessed, by qualitative and quantitative PCR, in ...
متن کاملThe Role of Human Endogenous Retroviruses (HERV-K) in the Pathogenesis of Human Cancers
Transmission of oncogenic retroviruses demonstrated in 1908. Much work was done around that period since by other researchers who demonstrated transfer of Sarcoma in chickens through filtrates. Although the name ‘retroviruses’ was coined as late as 1974, retroviral diseases were distinguished much earlier. Human endogenous retroviruses (HERVs) are natural components of the human genome and are ...
متن کاملERV-L elements: a family of endogenous retrovirus-like elements active throughout the evolution of mammals.
We have previously identified in the human genome a family of 200 endogenous retrovirus-like elements, the HERV-L elements, disclosing similarities with the foamy retroviruses and which might be the evolutionary intermediate between classical intracellular retrotransposons and infectious retroviruses. Southern blot analysis of a large series of mammalian genomic DNAs shows that HERV-L-related e...
متن کاملMultiple groups of endogenous epsilon-like retroviruses conserved across primates.
UNLABELLED Several types of cancer in fish are caused by retroviruses, including those responsible for major outbreaks of disease, such as walleye dermal sarcoma virus and salmon swim bladder sarcoma virus. These viruses form a phylogenetic group often described as the epsilonretrovirus genus. Epsilon-like retroviruses have become endogenous retroviruses (ERVs) on several occasions, integrating...
